ROUNDABOUT.

SPECIFICATION forming part of Letterslatent No. 739,691, dated September22, 1903. 7 Application filed January '7, IQlJS. Serial No. 13 8,17 7.(No model.)

To all whom it'may concern:

Beit known that I, OSCAR MANIG, a subject of the German Emperor, and aresident of Halle-on-the-Saale, Germany, have invented certain new anduseful Improvements in Roundabouts, of which the following is adescription.

The present invention relates to that class of roundabouts in which thecars containing the passengers describe a circular and at the same timeundulating path; and it consists in constructing the said path overwhich the cars run so that it may be revolved on a second circular path,on which the whole device is mounted.

In order to render the present specification easily intelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout the several views.

Figure l is a plan of the device; Fig. 2, a side elevation of the same,and Fig, 3 a side elevation seen from an angle of ninety degrees fromthat of Fig. 2. I

On the base or foundation or a oirc ular track I) is mountedpvhich liesin a horizontal plane. A second circular track e, having undulations, asillustrated in Figs. 2 and 3, is supported on suitable trolleys f and g,the former supporting the higher or elevated parts of the track andrunning on wheels 0 and the latter the lower parts and running on wheels61!. The cars or carriages h are of any suit-' able construction, andany desired number of the same may be coupled together; Any suitablemeans of the known types may be employed for driving the train of cars.

In order to rotate the undulating track on the horizontal one, thetrolleys f, supporting the higher parts of the track, may be provided 40with electric motors i and trailing contacts Z,

running on conductors lo, and the trolleys 01,

supporting the lower parts of the upper track and the intermittent partof the said upper track, may be utilized as a return-conductor,the'sections being suitably insulated, as will be readily understood. I

The object of the invention is to heighten the effect of suchroundabouts in that if the undulated track is turned in the direction ofmotion of the train the speed of the latter will be increased, while itturned in the opposite direction the speed will be diminished. Theincrease of speed is of great advantage, becausevat present it is notpossible to run undulating railways at a very great speed owing to thedanger of derailment.

I claim as my invention-i 1. In a roundabout, the combination of acircular undulating track and a circular horizon tal track mountedbeneath the same, wheels to support the former on the latter and meansfor rotating the undulating track on the horizontal one substantially asdescribed.

2. The combination of a circular undulating track, having a set ofwheels, a circular horizontally-disposed stationary track on which thewheels of the said undulating track run and electric motors to actuatesaid undulating track to rotate the same on the stationary tracksubstantially as described.

In witness whereof I have hereunto set'my hand in presence of twowitnesses.

OSCAR MANIG.
